The Torah reading Va’era (“I appeared”) covers Exodus 6:2-9:35.
Moshe (Moses) in Exodus 6 said his lips were “uncircumcised” and insisted that prevented him from sharing The Name of God to Yisra’el (Israel). We know about circumcision of a man’s privates and metaphorically of the “heart,” but what is this, and how is it connected to sharing knowledge of The Name?
Try to put yourself into Moses shoes here. His first presentation with Pharaoh doesn’t go very well—just as Moses had told God it wouldn’t. His confidence is even lower now than it was before. Yet God does not change His mind about his call on Moses and Aaron.
